BELL-RINGING KNOB.

Application filed July 8,

This invention relates to certain new and useful improvements in bell ringing door knobs and has for its primary object to mount a lever operated bell within a hollow door knob with the bell lever cooperating with the door knob to be shifted by the lat tor for ringing the bell upon rotary move ment of the door knob in either direction for sounding an alarm or to function in lieu of the usual door bell.

A further objectof the invention is to provide abell ringing door knob or" the above type wherein rotary movements of the door knob for ringing the bell is accomplished prior to the operation of the knob spindle for operating the door lock or latch mechanism, the door knob having limited rotary movement independently of the knob spindle and having connections win the op erating lever 01" the bell.

lVith the above and other general objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, com bination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawing wherein like reference characters are employed to designate corresponding parts throughout the several views Figure 1 is a side elevational view of a pair or" door knobs and spindles removed from the door latch mechanism Figure 2 is a longitudinal vertical sectional view showing the sounding alarm or bell housed within the hollow door knob.

Figure 3 is a vertical cross sectional view taken on line 3-3 of Figure 2, and

Figure 4 is a vertical cross sectional view taken on line 44 of Figure 2, showing the pin and slot connection between the door knob and spindle to permit limited rotary movements of the door knob independently of the spindle and the operating lever and slot connection between the door knob and bell mechanism.

The door latch mechanism and easing being removed, there is illustrated the knob spindle 1 having the opposite ends thereof extending into its angular bores formed in the blocks- 2 and so retained by the stud screws 8. The outer end of each block 2 carries a circular plate 4 to which a hollow knob is attached.

The knob is formed of two hollow sections 1926. serial No. 121,169.

5 and 6 of the general exterior of a door knob with the meeting circular edges thereof joined by a threaded connection as at 7. The knob section 5 is provided with a circular series of openings 8 for purposes presently to appear. 7

The connection between the door knob and spindle block 2 includes the formation of diametrically opposite arcuate slots 9 in the circular block plate 4 through which stud screws 10 extend for reception in threaded openings in the bottom wall of the knob section 5, this construction being clearly shown in Fig; 2 wherein Washer plates 11 are interposed between the heads of the stud 7 screws 10 and plates 4 to overlie the slotted openings 9. The bottom wall of the knob section 5 is mounted for rotary movement to be limited by the stud screw and slot connection by the pin extension 12 at each end 7 of the spindle 1 extending into a central opening in the bottom wall of the knob section. It will therefore be seen from an inspection of Figure 2 that the knob is permitted limited rotary movement independently of the spindle 1 at a distance equal to the length of the arcuate slots 9.

The bell ringing mechanism includes a bell 13 of the type having a finger lever projecting laterally thereof for operation of the bell ringing mechanism, the bell ringing lever 14 being of angle formation as shown in Figure 2. The lower side of the bell is anchored to the bottom wall of the knob section 5 by stud screws 15 threaded into the openings 16 as shown in Figures 2 and 4. The bell ringing lever 14 extends through an arcuate slot 17 in the bottom wall of the knob section 5 and has its outer end received in the notch 18 at the peripheral edge of the block plate 4 asshown in Figure 3. It will therefore be seen that when the knob is rotated, the same carries the bell bodily therewith and as the lever 14 is retained against movement by its connection with the plate 1 4, ringing of the bell is accomplished. The bell may be rung upon rotating the knob in either direct-ion and continued movement of the knob operates the spindle 1.

lVhile there is herein shown and described the preferred embodiment of the present invention, it is nevertheless, to be understood that minor changes may be made therein Without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, I claim 1. In a bell ringing door knob, the combination with a knob spindle having a block on the end thereof, of a knob carried by the block and having limited rotary movement independently of the spindle and block a bell carried by the knob and movable therewith, and a bell ringing lever carried by the bell and engaged by the spindle blooln 2. In a bell ringing door knob the co1nbination with a knob spindle having a block on the end thereof of a hollow knob carried by the block a pin and slot connection be tween the block and knob to permit limited rotary movement of the knob, independently of the block, a bell fixed to the knob interiorly thereof and a bell operating lever engaging the block.

3. In a bell ringing door knob, the combination with a knob spindle having a block on the end thereof, of a hollow knob carried by the block, a pin and slot connection between the block and knob to" permit limited rotary movement of the knob independently of the block, a bell fixed to the knob interiorly thereof, said knob having a slot therein and a bell operating lever carried by the bell and extending through the knob slot and attached to the spindle block. 7

In testimony whereof I afiix my signature.
